What is wrong with your network at Brampton area?

Could you be more specific please? What exactly is the coverage issue that you're having? Lte/4g? 3G? No signal at all?or just in certain location or buildings? The Telus/ Koodo network in the GTA is generally top notch, including Brampton.

What provider is the other Sim with? It's working fine in the same phone? Can you try swapping the Sims in both phones to see if the no signal issue follows the Sim card? It could be that you'll just need to go get your Sim card replaced.

One phone, two SIM cards. I tried all different combinations. I never experienced no such problems. It's today all of a sudden. I went to check the covered, no luck yet. Please help. I am paying so much to Koodo, but the experience has been bad.

HAHAHA Apparently, yeah! And see, I got to know so many things like, my phone isn't really compatible! Although I have been using it for 3 months now without any problem. It also gave me a chance to know how useful this forum is :-)
